Next-generation Viewpoint-based Environments 1 Viewpoint-based Environments

This paper discusses the notion of, and outlines requirements for Viewpoint-based Environments. These are next-generation CASE environments, which support the speciication of requirements from multiple perspectives or so-called viewpoints. Requirements for such environments are mainly concerned with the detection and management of interference between viewpoints. Viewpoint-based Environments sh...

- 1 - Defect Correction from a Galerkin Viewpoint

We consider the numerical solution of systems of nonlinear two point boundary value problems by Galerkin's method. An initial solution is computed with piecewise linear approximating functions and this is then improved by using higher—order piecewise polynomials to compute defect corrections. This technique, including numerical integration, is justified by typical Galerkin arguments and propert...

Viewpoint Selection using Viewpoint Entropy

Computation of good viewpoints is important in several fields: computational geometry, visual servoing, robot motion, graph drawing, etc. In addition, selection of good views is rapidly becoming a key issue in computer graphics due to the new techniques of Image Based Rendering. Although there is no consensus about what a good view means in Computer Graphics, the quality of a viewpoint is intui...
